IPC: C09K15/08
Filed: 1980-05-29
Abstract: PURPOSE: To synergistically enhance antioxidizing action of a ferulic acid ester to oils and fats, by the combined addition of the ferulic acid ester and an amuino compd. to the oils and fats.  
     CONSTITUTION: A ferulic acid ester of the formula (wherein R is a steroid group) in combination with an amino compd. is added to oils and fats. Although a ferulic acid ester is usually soluble e.g., in a liquid oil to an extent of up to 1.0W2.0%, it is unnecessary to add the ferulic acid ester to such an extent fecause sufficient antioxidizing action is exhibited at 0.1W1.0% or less, by use of the amino compd. in combination with the ferulic acid ester. Since said ferulic acid ester and the amino compd. are orally innoxious, they can be added to a product such as edible oils and fats or oils and fats to be used for domestic animals, or a processed product and cosmetics contg. a variety of oils and fats.

Abstract: PURPOSE:To enable an electric discharge current to be continually maintained within a predetermined permissible range, by enabling impedance of a discharge circuit to be selected into plural stages and supervising a change of the discharge current and voltage so as to adjust the impedance. CONSTITUTION:When a switching element 5 is turned on with an electric discharge current in a lower limit warning value or more, Schmitt trigger circuits 9, 10 are triggered, and impedance of a discharge circuit is held to a high value by turning off switching elements 16, 17. If the discharge current decreases to the lower limit warning value or less, the switching element 16 is turned on through the Schmitt trigger circuit 9, further if the discharge current decreases, also the switching element 17 is similarly turned on, and the discharge current is prevented from decreasing by short-circuiting R-S or R-T so as to decrease the impedance step by step. While reversely, if the discharge current increases to a high value, the impedance increases step by step by actuating the switching element 17 or 16, 17 so as to be turned off. In this way, an electrode is prevented from excessive consumption by holding the discharge current within a predetermined permissible range and eliminating the irregular interruption.
